Cache net images to the local disk. If an image is not cached in the local disk, download it from the network and cache it to the local disk. If an image exists in the local cache, load it from the cache.
Very useful for projects with a lot of images from the network.

“Fetch Image” node vs unreal's origin “Download Image” node.
- The “Download Image” node will download the image every time you call it.
- The “Fetch Image” node will only download the image the first time you call it, and the image will be cached to the local disk. The next time you call the node, the image will be loaded from the local disk, so it will be really fast.
